METAL POST.

Application filed December To all yiff/1,0m t may concern:

Be it known that l, ARTHUR l). dorms, a citizen of the United States, and a resident of Des Moines` in the county oit Polk and State ot Iowa, have invented a certain new and useful Metal Post, of which the following is a speciiication.

My invention relates to metal posts, preferably oi? galvanized steel.

The object ot my invention is to provide a post, made ot iron or steel, properly galvanized to prevent corrosion, and so constructed that the post can be readily formed to shape without destroying the galvanizing coat.

A 'further object is to provide a post made trom a single sheet ot metal formed into ahollow cylindrical tube, so as to have maximum strength with a minimum weight of material, with the edges of the sheet inturned, to leave no projections, secured to gether to make the post rigid and provided with simple staple receiving means.

Still another object 'is to provide a post of the kind mentioned having means for receiving ordinary standard staples at practically any height on the post, so arranged that the staples may be driven in in the usual way and will in the process ot' driving be bent to holding position, without leaving any exposed points capable of causing injury,

An additional object is to provide such a post having staple receiving means so arf ranged that the staples may be readily and easily removed without injury to the post, so that the wire on the post may be easily removed or replaced.

With these and other objects in view, my invention consists in the construction, arrangement and combination of the various parts of my device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claim, and illustrated in the accompanying drawings, in which:

Figure 1 shows a front elevation of a post embodying my invention. i

Figure 2 shows a side elevation of the same with the wire installed thereon shown in section.

Figure 3 shows, an enlarged, detail, vertical sectional view taken on the line 3 3 ot' Figure 1.

Figure l shows a plan view ot the sheet ont metal from which the post is made, part being broken away.

Figure shows a top view of the post.

Figure 6 shows a horizontal, sectional view taken on the line 6-6 of Figure 2.

Figure 7 shows a detail, vertical, .sectional view taken on the line 7 7 of Figure 2.

Figure 8 shows an inside elevation of a portion ot the post taken on the line 8-8 of Figure 5; and

Figure 9 shows a perspective view of a portion of the partly finished post just bei'ore the edges are fastened together.

My improved post is made from a sheet of metal, such as is shown in Figure 4t, the sheet being rolled to form a hollow cylindrical body, indicated in the drawings by the reference character 10. The sheet which have indicated as A, is bent along its side edges as at 11, along vertical lines equi-distantly spaced from the opposite side edges to 'form portions 12 which project inwardly from the body of the post adjacent to and parallel to each other, as shown in .Figure 5.

The post is shown in partly formed position in Figure 9.

The members 12 are secured tightly together by electric welding, rivets or other suitable means. They i'orm the means for connecting the edges of the post to leave a post which is smooth on the outside. They also afford a longitudinal reinforcing rib. Furthermore the members afford staple receiving and holding means.

When the sheet is in the blank, the portions 12 have grooves 13 stamped or otherwise formed in them, as shown in Figure 4l. These grooves are arranged to be opposite each other in the finished post to thus form staple receiving passages. In each portion or member 12, the grooves 13 are arranged in pairs with their outer ends practically communicating as shown in Figure 8.

From their outer ends, the grooves 13 of each pair are curved away from 'each other on the arcs of uniform circles of substantial diameter. The grooves 13 are so arranged that when the post is formed it has, along its vertical joint, a series of equi-distantly vertically spaced holes or passages, arranged at a distance apart corresponding to the distance between the arms or prongs of a standard fence staple 14.

The staple can then be started into any two adjacent holes and driven in. The staples will be bent enthe ares or' eireles either as shown at B or as shown at C in Figure 3, depending on what holes are used. The horizontal wire l5 of the enee will be held by the staple in the usual way.

The arrangement of the holes or passages formed by the grooves 13 is such that the wire l5 can be easily secured at any height on the post.

When it is desired to remove the wire` and the staples a sharp pair of nippers is used to eut the staple in two just at its middle point, and on aeeount of the curvature of the staple receiving passage on the ares of eireles, the half staples ear be easily pulled out in view of Jthe fact that their eurvature is on the same are of a eirele as the passageway. My post is very practical in view of the fact that the wire ilienee can be as easily Changed on it as on the ordinary wooden posts. j

It isobvious that even it the staples pro- Y' ject inwardly from the members 1Q. they can cause no harm to men or animals.

The `post may be made of galvanized steel, and its construction is sueh that the galvanizing willnot readily be injured. Its .shapel` that or a hollow strength.

The arrangement of the members l2 is such that they Connect the edges of the post rigidly together while permitting the post to retain its Cylindrical forni without project-` ing parts. They also form a strong` reinforcing rib. This is of special value in preventing the bending` of or serious injury to the top of the post when it is being driven into the ground7 since. the strong` rib-like members 1Q take a larg-e part of the impat olf the (haringblows. These members also provide means for the staple receiving passages.

Wire can be put on these posts or removed therefrom easily and readily, as etten may be desired without injury to the post.

l claim as my invention:

A metal post comprising a sheet formed into a hollow Cylinder with inwardly projeeting adjacent parallel strips at its edges7 secured together and forming' a longitl rlinal7 internal rib, said strips having ay sei-es ol.' corresponding adjaeent grooves :termine staple rereiving passages curved on the ares oi circles alternately toward and Jfrom eaoli other.
